Honda Civic Transmission, BMXA, Teardown Inspection 

BEST VIDEO ON HOW TO REBUILD YOUR AUTOMATIC 01-05 CIVIC TRANSMISSION ON RU-vid PERIOD!

Rebuilding my wifes BMXA out of a '05 Civic. I referenced this video constantly during teardown and rebuild. 10/10 video.

Hiram--thanks for taking the time to do this video in such a professional manner. I pulled a junkyard unit to rebuild for my daughter's Civic that had no motion in any gear. Between this and the factory manual, this was very doable! We'll rebuild her unit now that I've swapped it out with the one I rebuilt and it works perfectly! Your efforts are appreciated!

Hey man, just wanted to let you know, this video you did was awesome and I wanted to say thanks for putting this up. my transmission took a dump and I have never done a transmission before but this video saved me so much money and saved my civic. I had a few glitches but I finally got it back together after rebuilding it and I could have never been able to do it had it not been for this walk through. Thanks again, man!

I'd like to share what I've learned from this transmission. The first clutch pack you remove has thinner Steve plates then the other clutchpacks always remove the shaft end o-rings on the first clutchpack before splitting the case. And lastly I didn't have a puller like in your video so I tapped the whole assembly against a hard surface upside down and the pulleys came off. I used a section of steel pipe to tap them back on. Thank you so much for this great informative video. Without this video I wouldn't have had the guts to even take a closer look at this transmission much less do a full rebuild. Thank you and I will click the subscribe button

10 years later this video is still helping more than any other video. Thank you for making this. My only car is down right now and because of this video I am able to gear it running again

you explain things that would take a person years to learn and you make it look so easy, its actually fun to watch your videos.transmissions leave no room for error one tiny mistake and kaboom your back at it and spending more time and money it has to be apart of your daily work to get any good.you kids at home don't try this. ha ha ha. thanks again great video.

Thanks for putting this video out there. I'm researching transmission repair, specifically 2002 Honda's, and this has been a great resource as far as figuring out what's involved tearing down a transmission.

Fantastic video! My BMXA just went out and this is exactly what I was looking for. Thanks so much for taking the time to put these together, much much appreciated.

Great job illustrating the teardown of these transaxles. Certain that mine will need repairs soon. My head is reeling just how fast you had that apart. Take care.

Watching this I can immediately tell you are experienced transmission technician. Thank you for sharing your knowledge.

awesome video, never realized how complicated this stuff was

Sorry I left so many comments didn't mean to bug you. I already had the transmission in the car whe n I went to hook up the coolant lines and found the problem. I decided to take it all back apart and inspect. I didn't want a piece of coolant line wedged in between the bearing seat turns out it was threaded in too far without the coolant line on and the diferential just knocked it a bit. No biggie. Thank you for your video this is my first trans rebuild.

Thank you. I am looking forward to your BMXA rebuild next. I appreciate your site, great service.

You do an awesome job with your videos. It has help me many times.

When it comes to transmissions and automotive work there is so much to it now a days if you dont have a background in it, then its extreamly hard to get into, but if your driven and wanna do it, do it up!!! but for thes newer transmissions to work properly alot of other systems in a car or truck have to work properly,the amount this man knows about all the types of transmissions is amazing!

SR. HIRAN, MUCHAS GRACIAS POR COMPARTIRNOS SUS TRABAJOS, DE REPARACION DE TRANSMICIONES AUTOMATICAS Y MEJOR EXPLICADOS NO PODRIA SER, FELICIDADES SR. HIRAN.

I loved the way you explained everything little detail. I’m gonna go ahead and start taking mine apart and hopefully with your help it turns out good, thank you much 👍✌️✌️

That was it. We realized it after pouring over the manual for a long while. Thanks for the reply and thanks again for your videos. We finished reinstalling my transmission yesterday and it shifts better than it has the entire time I have owned the car.

thank you so much i rebuilt my 2002 covic lx auto transmission thanks to you and this tutorial i love it thanks man.

Nice Video Hiram, Thanks Again. Just did a B7TA with a blue converter and a ton of clutch material. Did all the Sonnax updates and the transmission shifts great. You're knowledge is much appreciated.

The close caption subtitles is ridiculously funny, but I really learned a lot from this video, planning on doing a full re-built on my Honda Civic 2001 Coupe as well... Gotta watch this video many times, looked up the Honda OEM Parts to compare all Part Schematics to the actually tear down component by component... 2 Thumbs up!! without any doubt, a Tranny Specialist

Awesome video! Very insightful, Thank You Hiram, great job

Great video Hiram !!! Keep up the good work.I'm going to attempt to rebuild the same transmission Honda Civic BMXA. I'm a mechanic by trade but this will be my first transmission rebuild ever.Thanks for posting all your videos they very helpful.

wow, there are so many parts to a transmission ! thanks for sharing !

thank you man for your hard work and i realy appreciated ; you are the man of the automatic i learned so much thank you and i will always fallow you work thanks man

Perfect video, I needed to know where to drill through the transmission case so I can absolutely blast the filter with brake cleaner till it works again.

Another excellent video. Looking forward to an assembly video. Thank you!

Wow, you are a pro!! Thanks for the videos. Very informative.

Thanks Hiram, I've been waiting for that one.

Thanks so much.You are doing a great service for explaining every part.

great vid by the way. I referred to it just once or twice during my build ;)

Nice video. I am an ASE certified auto mechanic with 22+ years of experience; I never rebuild automatic transmission myself neither any auto repair shop that I worked rebuild automatic transmission; we always sanded this cars to an automatic transmission shop. At only one exception at the dealer where I worked they had one mechanic specialized in automatic transmission and they use to give all the automatic transmission repair to that mechanic only; and it’s the same with all the dealers. Now days many dealers won’t even do that they have their national rebuilding center so they order a rebuild one from that center and sent the old transmission back to that center to be rebuilt and put it on the shelf, they’re doing the same thing with the engines, they figured it's better and quicker.

thank you so much fordoing this particular tranny work and posting the video. im having trouble with shifting in my bmxa trans automatic and this will def help me. again thank you mann

Thank you for the information it has helped me a lot!

Very helpful video. If you watch this video AND his video Titled "Honda Trans Rebuild Video - Trans Repair" You should have no problem rebuilding your BMXA trans. Second video is of an Accord, But the same techniques goes into 4spd. Like how to install orings & clutch packs. My rebuild kit, filter, TC, honda fluid & a couple seals cost me about $250. Thanks Hiram!!!

Your videos helped so much, mission accomplished! Right to repair!

Your the shit bro! Banged out an SLXA with this guide. Good form

Love your videos

Exelente video saludos desde Rosarito Baja California MX. Gracias por el video y la explicasion tan completa.

Great video sir 👍, helping alot of people out there with this video me included, having the issue with my automatic 04 civic dx after a few minutes the car will just rev and not go into gear. Gotta turn off the car wait abit and works again. But awesome stuff sir thanks 🤙🏽🤙🏽

Thanks for the video, very informative.

YOU ARE THE BEST ON RU-vid

I like the way your talk me through it

gracias por su video maestro, el dia de hoy yo desarme una caja de esas y me sirvio ver su video , supe que las tuercas de los ejes eran rosca izquierda, felicidades, gracias

Hiram por favor As los vídeos en español también. Soy de Colombia y es muy difícil aqui encontrar guías y tutoriales. Tu me as guiado en demasiadas ocasiones. Mil grx hiram!

Dios lo bendiga! Hiram por estos excelentes videos.

Great Video ......Now If I Only Knew How To Put It All Back Together, Please Upload A Reassembly Video .......And THANK You For All The Info You Provide

great videos Hiram. In your video, was there a spacer plate in between the main valve body and the regulator valve body? working on a b4ra and not sure if there was a spacer there or did I misplace it. Keep up the great videos

very good thank you very much for your effort and help

Thank you very much for this wonderful video I really learnt a lot I repair automatic gearbox in Nigeria African

thank you for sharing!

Great video

Hi Hiram, Thanks for the video... It's given me the guts to refurb mine! One question though... what's the torque setting when you but all the bolts back on ? Thank you!

Great video, thank you!

Hello sir, videos are great and you explain things very well. Would you happen to have a honda/acura b-series manual transmission that you could do these kind of videos on? I'm wanting to learn the procedures to do it but can not find anything like what you do, thanks for your time.

I'm doing my first bmxa rebuild at home next week and wondering what special tools I will need to order I'm a tech at the Honda dealer so just have my normal tools .

Hiram,your vid gave me confidence to rebuild my BXMA. After install I had all gears but my shift indicator lights are not in sync with the shifter. Manual says to make sure range selector switch is synced so i am assuming to fix my problem I adjust it to fix this. Thanks Hiram great instruction and great videos.

Thanks for sharing your knowledge Hiram. Do you recomend external filters with your rebuilds? Or is the oversize filter enough to remedy the problem? Thanks again for the vids and expertice

Nice video ! Thanks!

Awesome video Hiram!! Question, what are the torque specs for the valve body bolts? I'm reassembling mine but am unsure of how tight the bolts should be. - Thanks again!!

muchas gracias amigo,,,,,me sirvio de mucho. Saludos

thank you...!! Great teacher !

Great video, thank you again for posting them. Keep up the good work!

Great video, I learned a great deal from this demonstration. When I removed the upper valve body I found that one of the springs was broken 1/4 of the way. What is the critical functionality of the springs. Does it only open up during high pressure. How should I go about getting a replacement.

Thank you so much would’ve never been able to do this without your video!! I do have one question tho I need one of the 15/16 left handed nuts and I can’t find them no where do you have any suggestions?

thanks hiram for teaching my son (19 yrs) - aloha

This video is great, I have watched it through a few times. Im thinking about taking this on due my 03 does the reving up between gears when it's cold and a shuddering is starting at lower speeds at lock up. Do you recommend that I get a kit that has the oem friction materials? I've heard that the aftermarket ones can cause problems.

Hiram, thanks for the video, but I took apart but got lost on the location of the pipes is any way we can get a location on the pipes please

Thanks for this awesome video. We have used it along with some of your other videos to rebuild my BMXA transmission. I have a question for you though. We are repacking and installing the first clutch pack and we can't get the snap ring on without really forcing it. The clutch plates don't move freely like the other ones did. We did verify that the piston is seated correctly. Is it normal/okay for it to be this tight? did we do something wrong? Thanks again

Are there any Sonnax upgrades recommend for the BMXA transmission, in the other Honda rebuild videos Hiram recommended O-Ringed end plug kit, TC Check Valve and Pressure regulator valve as upgrades. I can only see the end plugged Kit on the Sonnax site for the BMXA transmission. Also what rebuild kit are you guys using/recommend want something with everything in it the Raybestos GPX frictions look like a step up. Wish there was a detailed rebuild video just as good as this teardown for the BMXA transmission. Really enjoy his videos straight forward and informational really learned some good info.

Hello Hiram, you are very detailed with your work! Awesome job.... I have a question...I have a 2001 civic lx automatic and it has a hairline crack by the transmission drain bolt (guess from over tighten it)....I do have a spare transmission...Now do I have to take off the solenoids etc...in order to replace the transmission case? Or just take off the bearing on top and the main bolts? Need help Danny NYC

I have a 2002 civic lx just got done rebuilding trans. but the revers is stock doesn't want to move is just feels like stock the more rpm (2500) seems to move a little. driving forward drive like a champ.

Hi Hiram. Great video. I'm rebuilding a b4ra on a 98 civic lx. It looks identical. At 22:38 you remove a snap ring. I'm having trouble putting that snap ring back in and because of this, the mainshaft does not freely rotate when the casing is torqued to spec. Does that clip need to fit into a groove on the shaft or does it nestle into the thrust bearing. Thanks for sharing your expertise. Because of your work I think my rebuild will be a complete success. (Once I figure out the snap ring issue). Thanks for sharing.

hello i appreciate the video you made for this transmission, i was wondering if you possibly have an extra main shaft for the BMXA transmission that you are willing to sell

Great Video, Can you tell me what makes the transmission feel like it goes into neutral when i stop at a stop sign or red light? Thanks again

Hiram do you have a install video and what is a good rebuild kit to purchase? GOOD VIDEO THANKS

Ufff... excellent video. Thx

good information these automatics are not as scary as i thought.

i just did a shift kit on a 05 H Civic, a BMXA tranny, and a complete overhaul, rebuild torque converter , 5 days later the costumer complain, no revese and no 4th gear.. the 2-4 drum was burn. no dtc¨s.. I appreciate your knowledge and help. Gracias.

Can you remove the solenoids in place to clean the screen or would you need to drain the ATF first? Great videos. Learning a lot, thank you.

Okay I messed something up after taking off the coolent lines I threaded them back in the case and bent the end of the coolant bolt that goes in above the differential does the end of this bolt go directly into a passage or is it just a return. Will it still work or do I need to find a new bolt

Gracias proxima semana boy a armar una y tu video medio valor gracias

Great video! But do you recommend sonnex PR reg. valve and O-ring aluminum plugs for BMXA?

Great Video. Thanks. I hAve a question . What would cause it to start off in 2nd gear when putting it in drive. When I select 2 , it starts if 1st gear like it’s supposed to Thanks again

Great video . I have a question in reference to the tubes. How do i know which tube goes where if i did not keep track of this during disassembly?

amazing

Dear Hiram, thanks for this great explanation and instruction, I would like to ask you, I have the same transmission for honda CIVIC 2005, after changing the Disks, Clutches and assembled the Transmission, I got the following problem in the gear which is when I run it and put the gear I got the first gear and goes directly to to gear 4, so it by pass the second and the 3rd. so do you have any suggestions??? Thank you in advanced. Rabih

I have 2 questions. The clutch that you opened up on 24:26 of this video. The clutch on the main shaft closest to the torque converter. Was missing an internal washer in my transmission. All the other clutches in my transmission after removing the final steel plate had what looks like a huge cut washer. When I assembled the clutch the plates had a lot of play. Not like the other clutches in my transmission that were nice and snug. It looks in the video like the ring is missing on the trans you opened as well. Is this normal? P.s. I could tell by wear marks this ring has been missing. It's this why this clutch burns first? Sane as in your video. My second question are all the clutch disks and plates the same size? Because my kit came with a bunch in one package. It wasn't until I rebuilt the 1st clutch. That the steel plates were thicker

Its good that all electronc controls are outside on honda transmissions.. but biggest negative is internal filters. I believe that cause all the problems in these transmissions. If they were easy to replace like many other manufactures, they would last longer than they do..

I noticed that there are a couple different types of filters available. A felt and a screen type. Which one is preferred?

What a great vid sir.... ...a QUE please Can u please tell us WHAT trans fluid do YOU put in these BMXA trans....and Honda in general...some of us want to run Valvoline Max Life (full synth) what are your thoughts Thanks

I have a issue after the rebuild my car won’t go in reverse and it goes forward in neutral! Any ideas guys I would really appreciate!

Hola hiram muchas gracias por los videos este en particular,me gustaria hacerte una pregunta.... la transmission de un civic non vtec funciona en un civic vtec? muchas gracias nuevamente

hi. Where can I get the updated version of the transmission filter. also are there any non oem plates for the clutches. or it is ok tu use oem plates for the clutches?

Hello Thanks for the great videos. I have a 2002 civic bmxa . Can you suggest a book or manual for the transmission. I need more info on which solenoid does what....... I had a burned up 4th friction pack. the trans would not go to first when put in drive. the 4th gear friction pack i had to pry out with a screwdriver it was so distorted. Had to manually move the shift selector to get the car moving. I overhauled the unit and replaced all the frictions and O rings...all the valves are free. Had the torque converter rebuilt too. everything in side the case looks just fine. I'm thinking I have a bad sensor or control module. Put the car back on the road it drove great but after 5 miles its doing the same thing again...not going to first from a full stop. Is there a book or text you can point me to that gives a good tech description of how to trouble shoot this thing.... Thanks for any help you can offer.....Rich Pearsall rjpsails@hotmail.com

One more question what sealant would you recommend for the paper gadgets? Or is it better not to use sealant

Hiram, awesome video, I learned alot. I rebuilt my transmission works and shifts great, but I am not getting lock up. I have the dreaded p0740 after rebuild. Any help would be appreciated thank you.

thank you Harold

hi!! i have a question. the internal bolts from the the aut transmition bmxa have an especifical torque? this us because i am changing the filter my self. thanks in advance for your time and help.
